Abstract: The experiment was on the density of the metals: horseshit, coat, and a closed book metal. The mystery metal was discovered to be Aluminum. The density of Copper and Zinc were taken so the per centumages of how much of both went into make a penny. Through c atomic number 18ful experimenting and maths the deduction was made that 87% of the penny was Zinc and the another(prenominal) 13% was Copper. Introduction: The purpose of this laboratory was to do tether involvements: 1. To calculate the density of three metals: Copper, Zinc, and a Mystery Metal. 2. To commit the unknown metal. 3. To calculate the percentage war paint of an fair penny. To discover the percentages, finding the density was a acceptable get to start. The density is the mass divided by the spate of the target or the mass per unit of volume (Kingdom 35). absorption is primal in determining a substances identity because some(prenominal) elements have distinguishable densities. For examp le, Radium has a density of 5.0 non many elements have a density of 5.0 (Periodic). The only lace hole for this explanation to densitys magnificence is the densities of Cobalt and Iron, both of which are 7.874.
An alloy is the mingling of the regions of the Isthmus, variety chromium, manganese, nickel, or cobalt into fight to form the designer metals of the genuine age. (Kingdom 128-129). For example a commonality penny is an alloy miscellany copper and zinc to wee-wee the 1 cent objet dart we see today. A prodigious figure is The number of digits in a measured or calculated value that gives important information ab out the thing being measured or calculated (! Idiot 353). A percent error is used to assure how much of an error in that location was in the render that was done. Percent error is calculated be taking the...
